Unfortunately not. Unlike the other styles I disabled that threw errors
on startup, the bw-noicon didn't show any obvious errors.
The problem was that the mapnik backend died frequently and if all
backends died, tirex-backend-manager appears to go into a livelock. The
logs showed that the last tile processed was a bw-noicon and after I
disabled it, the issue went away.
I have re-enabled bw-noicon now though at we'll see if the problem
reappears or if it was caused by something else and just coincidence.
Since it is
automatically derived from the original osm-mapnik
I am a bit reluctant to introduce any manual changes, but
if it helps speeding up rendering, I'm trying.
For low zoom rendering, it would be good if you can try and use the "no
buildings index" on the planet_polygon table. I will try and make those
changes on default style as well, so perhaps you can rederive it from
However I could need some more hints about where the real
trouble occurs with the style.
